LG G5 does not turn on but the CPU heats up

It's probably the plus and minus of the battery contacts. Measuring won't hurt it so you can't really screw up.

The CPU isn't heating up anymore, for some reason, and the battery is reading normally at around what it's supposed to be at.

I took apart my LG g5 because it would not turn on whatsoever and the second I plug the battery in, the heatsink for the CPU, ram, and stuff starts heating up, nothing shows up. I don't know the pins for the power button so I just shorted all of the pins coming from the fingerprint sensor, not sure if that would cause it to fry or something. None of the liquid damage indicators show anything but there's this weird stuff under the main camera, shown in the picture.

Short circuit is never a good idea if you are not sure what you are doing. For me it sounds like a problem with some power delivery circuit being damaged so that it delivers too much voltage to the components which makes them hot but not functional. In my experience phones with similar issues have been using replacement batteries and they probably were the issue. If you have any way of measuring the voltage, it would help a lot to solve this problem.

I think I can measure it, where would I measure the voltage from?
